Abstract

To clarify how the condensation on the covering materials of row covers changes their porosity and longwave characteristics, an experiment on the changes in porosity due to condensation was conducted, and the changes in longwave characteristics due to condensation were calculated. The results showed that condensation increased the emissivity of the covering materials up to 100% compared to that of dry materials.
